classic waka stream

Gathered up and looked
at, they come to nothing—these
salt-weeds of hers; so
let them be smoke and go up
into that same sky as she

Meaning
Gathered up and looked at, they come to nothing—these salt-weeds; let them be smoke and go up into the same sky as she did.
Commentary
Part Two: Maboroshi

 After weeping over her letters, Genji at last had the women tear them and put them into the fire, and they went up as smoke. He spoke this poem to himself. Kept, they might be seen by others, and they would go on unsettling him. Turning them all to smoke, he cut his ties with the world one by one. Only the year-end rite of the Buddhas' names remained, and the tale moves toward the last day of the year.

 "Gathered up" is raking things together. "Come to nothing" is being of no use. "Salt-weeds" is the seaweed collected for salt-making, used here for the heaped-up letters, and it belongs with gathering and with smoke. "That same sky" is where the smoke of her pyre went. "Let them be smoke" is a command. The burning of the letters is reread as the act of sending them after her.
